Physics I

Course developer

Course abstract

The aim of this course is to provide knowledge in physics, from mechanics to electrostatics and direct current, in accordance with the needs of further professional studies of energy engineers and machine design specialists, because physics is the basis for understanding of all natural and engineering sciences. Course of Physics consists of two parts and it is mastered within lectures, practical classes and laboratory works. The knowledge of Physics is essential for understanding of processes in energetics correlations in Physics, forms the basis for new innovations in economy. By solving the exercises in Physics the analytical thinking is developed. Modern specialists should know the basis of Physics for developing the worldview and creative use of physical correlations in practical activities.

Learning outcomes and their assessment

After completing the course students will have:
1. knowledge about regularity of essential concepts of physics and critical understanding of how to use it in real-world process description. – The knowledge is assessed in laboratory works and tests.
2. skills to use measurements of physical quantities and apply knowledge in calculation for their branch of research, summarize and analytically describe the results. – The skills are assessed in laboratory works.

3. competence to evaluate results of measurements and calculations, problem solving and understand what influence their professional activities have on environment. – The competence is assessed in laboratory works and tests and exam.

Requirements for awarding credit points

Passing the test (min. 50% of maximum points (each test – 10 points).
Laboratory works must be performed and defended.

Description of the organization and tasks of students’ independent work

Preparing to test.
Each student must process the experimental data obtained during the laboratory work (it is necessary to perform calculations in accordance to the assignment and, if required in the assignment, to plot a graph), and document the results in accordance to the requirements, as well as prepare for the defense of laboratory work by independently studying the study literature.

Criteria for Evaluating Learning Outcomes

1.Evaluation of study results is based on student’s results in tests -3:
2. Performed and defended laboratory works – 8.
